CVE-2026-55629: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in avwo whistle
CVE-2026-55629 is a path traversal vulnerability in avwo whistle, a debugging proxy for HTTP and related protocols. Versions prior to 2.10.3 improperly handle user-supplied filenames in a GET request to /cgi-bin/temp/get, allowing attackers to read arbitrary files on the server. The issue is fixed in version 2.10.3. The vulnerability has a high severity with a CVSS score of 8.7.
AI Analysis
Technical Summary
In avwo whistle versions before 2.10.3, the file lib/service/service.js processes GET requests to /cgi-bin/temp/get by reading the filename parameter from the query string. If the filename matches a temporary file pattern, it is joined to a restricted TEMP_FILES_PATH. Otherwise, the filename is passed directly to the getFile function without restriction, enabling remote attackers to perform path traversal attacks and read arbitrary files such as /etc/passwd. This vulnerability is addressed in version 2.10.3.
Potential Impact
An unauthenticated remote attacker can exploit this vulnerability to read arbitrary files on the affected system by supplying crafted filenames in the GET request. This can lead to disclosure of sensitive information, potentially compromising system security. The vulnerability does not require user interaction or privileges and has a high impact on confidentiality.
Mitigation Recommendations
The vulnerability is fixed in avwo whistle version 2.10.3. Users should upgrade to version 2.10.3 or later to remediate this issue. No other mitigation or workaround is specified.
